This is a simulation of an alternative monetary system backed by real goods and services, rather than debt, based on the Digital Coin proposal by Paul Grignon.
Producers issue themselves with credit based on promises of future production.
These credits are then used as money, eventually redeamable with the issuer for their goods or services.
No banks, no interest, no growth imperative, no inflation. For real?

What if I don't produce anything?Then you have no basis upon which to issue yourself with credit.

Is this for real?Of course not. Real money comes from a bank, silly. That's why we need banks. They create money for us, based on our promise to repay it. It's complicated. Let the bankers handle it. Now get back to work.

But what if people actually started trading with Digital Coins?Then it would become a new form of money.
